TIFF files can contain more than one image. If all=TRUE then all images are returned in a list of images. If all is a vector, it gives the (1-based) indices of images to return. Otherwise only the first image is returned. convert logical, if TRUE then first convert the image into 8-bit RGBA samples and then to an array, see below for details.
